I came to find out over the years that after Bob Knight was fired by IU that the rivalry died then for me. It was not as much fun playing or beating IU after Knight was gone. It was so much fun watching him stalk off the court after his team lost. He was like a spoiled child taking his ball and going home after not getting his way. That's been gone for a long time and will never be re-captured again.
But all rivalries have died for me now. I am in the process of divorcing myself from college sports. I hate the way it has turned with transfers and NIL. Just no pleasure for me anymore and with the genie out of the bottle it will never go back to being close to the way it was before. Like many divorces I may go back for short times again to watch a little, mainly out of habit, but over time things will drift away and I will go to other interests and things that make me happier.
